The shape and specification of drainage ditch mold can present many different styles, mainly for the purpose of producing standard prefabricated parts for better application to high-speed construction. First, the shape and style of the mold are introduced. There are four kinds of shapes, i.e. U-shape, rectangular shape, trapezoid shape, dish shape, etc., all of which have good drainage effect, but dish shape The trapezoid and trapezoid drain molds are basically made of plastic, but most of the rectangular and U-shaped molds are made of steel molds, so the selection of mold material should also be based on its shape and style for reference. In addition, the drain plastic molds are not only variable in shape, but also uncertain in specification, especially the dished drain, almost every height The size of the dished drains used on both sides of the expressway is different, generally two or three prefabricated parts are spliced together for use, but for a single drain plastic mold, it is made through the drawings provided by the construction party, and for this kind of spliced product, it is very suitable to use plastic materials for production, first of all, it is very expensive The budget of low and no increase project cost is mainly due to the convenience of its operation, which wins the hearts of many construction parties. The production mode is simple and efficient.
The drainage ditch mold is very easy in the production process, but the details of the mold production should be controlled. Many professional technologies are used in the production of the mold, such as cutting, bending, welding, etc., especially the steps of bending need to have certain technology and equipment to make the arc of the steel plate meet the needs of the mold production. The bending method is also relatively easy to manage The solution is to use external force to fold the steel plate into the shape we need, which is generally widely used in agriculture and water conservancy. After having a preliminary understanding of the operation method of the rectangular groove mold, it can be used. The operation method is also very simple. Before using, check the mold's style, shape, state and supporting parts, etc., and then mold Spray a layer of oil on the internal and external molds of the tool after assembly, so that the molds are always lubricated in the production process, so that they will not coagulate on the molds after pouring concrete, and then vibrate on the platform with larger size. The purpose of vibration is to achieve the effect of compaction and sedimentation of the slurry. Generally, the oversized rectangular groove molds coagulate on the concrete The time will be longer, and the hardness of cement will affect the integrity of demoulding.
